In the pilot, he actually picks up an assault rifle he 'borrowed' from a guard and opens fire around a group of them to buy a little time to prepare a parachute. He dosen't hit anyone, though you can't tell if he's just shooting to scare (as I'd imagine the case is) or he's just a lousy shot! <img src="/images/graemlins/crazy.gif" alt="" /> And a favorite trick of his I've seen is to rig up guns to shoot on a delay or tripwire. First few discs alone I remember he set off a rifle for distraction, and set off a LOT of rifles to blow the tires out of a bad guy's jeep. And in one mid-first-season ep, he clobbers a killer with an M-16. The killer pulls out a knife and Mac picks up the rifle and uses it to block the stab.
I did some research and read about the flashback episode...where I read it claimed that Richard was going to do an anti-gun PSA at the end of the ep, but backed off because the NRA didn't want him to? Sounds fishy, did the NRA steal the script or something? <img src="/images/graemlins/tongue.gif" alt="" />
